It isn't just the best team in the East that's vulnerable: History suggests that Chicago could also face a first-round upset.

The Blackhawks opened the season with 24 consecutive games (including a franchise record of 11 straight wins) without losing in regulation, crushing the previous mark of 16 by the 2006-07 Anaheim Ducks and leading to Chicago's first Presidents' Trophy since the 1990-91 season.
